INSPECTION, TESTING AND MAINTENANCE
GENERAL
H. Replacement rope shall have a strength rating
at least as great as the original rope furnished
or recommended by the crane manufacturer.
Any deviation from the original size, grade, or
construction shall be specified by a rope
manufacturer, or a qualified person.
35. Rope not in regular use: all rope which has
been idle for a period of a month or more due
to shutdown or storage of a crane on which it is
installed, shall be given and inspection in
accordance with above information before it is
placed in service. This inspection shall be for
all types of deterioration and shall be
performed by a qualified person.
36. Inspection records
A. A. frequent inspection- no records
required
B. A. periodic inspections- in order to
establish data as a basis for judging the
proper time for replacement, a dated report
condition at each periodic inspection
should be kept on file. This report shall
cover points of deterioration listed above.
ROPE MAINTENANCE
37. Rope should be stored to prevent damage or
deterioration.
38. Unreeling or uncoiling of rope shall be done as
recommended by the rope manufacturer and
with care to avoid kinking or inducing twist.
39. Before cutting a rope, seizing shall be placed
on each side of the place where the rope is to
be cut to prevent unlaying of the strands. On
pre-formed rope, one seizing on each side of
the cut is required. On non-preformed ropes of
7/8 in. (22 mm) diameter or smaller, two
seizings on each side of the cut are required,
and for non-preformed rope 1 in. (25 mm)
diameter or larger, three seizings on each side
of the cut are required.
40. During installation care should be exercised to
avoid dragging of the rope in the dirt or around
objects which will scrape, nick crush or induce
sharp bends in it.
41. Rope should be maintained in a well-lubricated
condition. It is important that lubricant applied
as a part of a maintenance program shall be
compatible with the original lubricant and to
this end the rope manufacturer should be
consulted. Lubricant applied shall be the type
which does not hinder visual inspection. Those
sections of rope which are located over
sheaves or otherwise hidden during inspection
and maintenance procedures require special
attention when lubricating rope. The object of
rope lubrication is to reduce internal friction
and to prevent corrosion.
42. When an operating rope shows greater wear or
well defined localized areas than on the
remainder of the rope, rope life can be
extended in cases where a section at the worn
end, and thus shifting the wear to different
areas of the rope.
